Given numbers are 665,856,517,204
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,856,517,204 is 15009151080.
Find LCM of 665,856,517,204 with Prime Factorization
| 2 | 665, 856, 517, 204 |
| 2 | 665, 428, 517, 102 |
| 665, 214, 517, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 665 x 214 x 517 x 51 = 15009151080
Therefore, the lowest common multiple of 665,856,517,204 is 15009151080.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
665 x 856 x 517 x 204 = 60036604320
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
665 : 1, 5, 7, 19, 35, 95, 133, 665
856 : 1, 2, 4, 8, 107, 214, 428, 856
517 : 1, 11, 47, 517
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,856,517,204, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
856:2x 2x 2x 107
517:11x 47
204:2x 2x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 60036604320/(1x4)
LCM = 60036604320/4
LCM = 15009151080
Thus, we can understand that the LCM of 665,856,517,204 is 15009151080.
